Sun needs to get back to making the best mid to high tier hardware in the industry thats what got them where they were. Their high end stuff was considerably less costly than IBM's RISK offerings but that is no longer the case. I have had more trouble with the little bit of Sun and Sun re-branded equipment in my shop over the past three years than I did with the hundreds of sun servers I was running at a previous company from the late 90's to 2003.
The easy days of competing mainly against IBM are over, now they compete with MS, HP, IBM, RedHat, and Novell (And down the line maybe Apple) All of whom are serious players in the server market. I really hope they turn it around...
